SPRacing H7RF FC with ExpressLRS

Dominic Clifton, the creator of the Cleanflight and SPRacing brand, has designed a new top of the line flight controller SPRacing H7RF. Board has H730 MCU, the fastest currently on the market, running on 520MHz operating frequency. H7RF has TDK ICM42688P gyro and ExpressLRS 2.4 GHz Long Range receiver on board. This flight controller has graphic PixelOSD overlay on the video feed as well as RealPit switch. There are also 5 UARTS2x 4in1 ESC sockets, SD Card slot, Flash chip for firmware and many more. The SPRacing H7RF board can be mounted in 30x30mm and 20x20mm stacks.
